Yoctonewtons Of Force Measured

The smallest ever measurement of a force has reported {link open only for a limited time}.

The result, measuring mere yoctonewtons (10–24 newtons), beats previous record lows by several orders of magnitude. The group behind the measurements, based at the National Institute of Standards and Technology in Boulder, Colorado, hopes that the technique can eventually lead to new tools for measuring the minuscule features of materials' surfaces.

The preprint cited can be found here.
